Make your Internet of Things device cable-free by adding WiFi. Take advantage of the Raspberry Pi and Beagle Bone's USB port to add a low cost, but high-reliability wireless link.
Add a miniature wireless controller to your computer project with this combination keyboard and touchpad. We found the smallest wireless USB keyboard available, a mere 6" x 2.4" x 0.5" (152mm x 59mm x 12.5mm)! It's small but usable to make a great accompaniment to a computer such as the Beagle Bone or Raspberry Pi.
The cable is easiest way ever to connect to your microcontroller/Raspberry Pi/WiFi router serial console port. Inside the big USB plug is a USB<->Serial conversion chip and at the end of the 36" cable are four wire - red power, black ground, white RX into USB port, and green TX out of the USB port.
Add Bluetooth capability to your computer super fast with a USB BT 4.0 adapter. This adapter is backwards compatible with v2.1 and earlier, but also supports the latest v4.0/Bluetooth Low Energy. Inside lies a CSR8510 Bluetooth USB host.
The IRKey adds an IR remote receiver to any computer, laptop, tablet...any computer with a USB port. This little board slides into any USB A port, and shows up as an every-day USB keyboard. The onboard ATiny85 microcontroller listens for IR remote signals and converts them to keypresses.
This is the assembled version of the Pi T-Cobbler Plus. It only works with the Raspberry Pi Model A+/B+/Pi 2!
